First baseman Brandon Snyder and left-hander Troy Patton have joined the Orioles in Boston, and though neither has been officially activated yet, the team is likely to make room for both before the game.

Lee suffered a strained oblique during Monday’s game against the Red Sox. It’s awful timing for him, as he seemed to be warming up in the plate. He doubled in one of his two at-bats Monday, extended his hitting streak to six games and giving him four RBI in the last three games.

Snyder would likely share time at first base with Luke Scott while Lee is out. The former first-round pick was hitting .276/.342/.455 with five homers in 134 at-bats for Triple-A Norfolk. Most of his production came against left-handers, so the Orioles may want to use him in a strict platoon.

Patton, being used primarily as a reliever for the first time, had a 2.60 ERA in 17 1/3 innings for Norfolk. Although he’s a lefty, left-handers were hitting .286 against him, whereas righties were at .208.
